Description

Hexanedioic Acid, Polymer With 1,3-Diisocyanatomethylbenzene, 1,2-Ethanediol, Methyloxirane, Oxirane And 1,2-Propanediol CAS NO 125329-07-9 is a specialized polyurethane-polyol hybrid polymer, engineered for high-performance applications requiring tailored reactivity and physical properties. This compound matters for its versatility as a reactive intermediate, offering formulators precise control over final product characteristics such as flexibility, adhesion, and chemical resistance. It is primarily needed by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in advanced composite and specialty resin production.

Application

• High-Performance Polyurethane Coatings: Used as a key resin component in industrial, automotive, and protective coatings for enhanced durability and weather resistance.
• Adhesives and Sealants: Serves as a backbone polymer in formulations requiring strong bonding, flexibility, and resistance to environmental stress.
• Elastomers and Castable Urethanes: Provides the foundational chemistry for producing flexible, abrasion-resistant, and load-bearing polyurethane parts.
• Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced plastics (FRP) and other composite systems.
• Specialty Resins and Binders: Utilized in formulating advanced binders for foundry, construction, or electronic encapsulation materials.
• Reactive Diluent and Modifier: Functions to modify the viscosity, cure profile, and final properties of other polymer systems.

Quality Control

Our production of this advanced polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including hydroxyl value, viscosity, acid number, and color to meet precise customer specifications. Certificates of Analysis (COA) documenting all test results are provided and available upon request, supporting compliance in regulated supply chains.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). This material is moisture-sensitive (hygroscopic); ensure containers are sealed after each use to prevent absorption of atmospheric moisture, which can affect reactivity and properties.
